2O MEMOIRS ON THE COLEOPTERA 



The four homogeneous examples, kindly communicated by Mr. 

 Criddle, represent a form allied to lecontei but very much stouter, the 

 head similarly hairy in the male but with the erect hairs on the flanks 

 of the prothorax longer, much more numerous and conspicuous, 

 especially in the male; the outer margins of the elytra as a rule 

 are broadly and continuously white throughout and not resolved 

 into three widely separated sections as in lecontei and modesta. 



9 The fulgida group, as here organized, contains but few dis- 

 cordant structural elements, and for the most part holds together 

 very well in its chief distinguishing feature among the neighboring 

 groups, that is the very short tarsi ; these are longer in fulgida than 

 in any other species of the group but not so very much longer, and 

 cochisensis, though having the characteristically short tarsi, is con- 

 spicuously different in its immaculate elytra, there being no spot 

 except the humeral which is occasionally evident. All collections 

 contain a form of latesignata in which the broad elytral marking 

 becomes in great part confluent, leaving only the suture, very 

 broadly basally and abruptly expanded in a transverse spot near 

 apical fourth, dark. This form has never been named but, as there 

 are no intermediates and the taxonomic value of the form unknown, 

 it seems best to give it a definite designation as follows: 



Cicindela latesignata ssp. obliviosa nov. Similar to latesignata in 

 form, color and sculpture, excepting that the pale markings of the elytra 

 are broadly confluent. Length (cf 9 ) 12.5-13.0 mm.; width 4.8-5.2 mm. 

 California (Seabeaches at San Diego, occurring apparently with the 

 normal form of the species). 



The constancy of this aberration is quite as inexplicable on the 

 ground of mere variation, as is that of the pale form in some species 

 of the dorsalis group. It is possibly a case of asexual dimorphism, 

 but its real nature is not known. As a rule the outline of obliviosa 

 is a little narrower than that of latesignata and in those rare exam- 

 ples displaying a slight separation of the markings, it will be ob- 

 served that the humeral lunule is more oblique or less transverse 

 posteriorly than in latesignata. 



Cicindela limbigera ssp. nympha nov. Nearly similar to limbigera 

 but larger and with larger head, the color darker aeneous-brown and 

 not blue or green as in that species; head and prothorax with similar 

 plentiful bristling white pubescence; elytra similar in form and sculpture
